Application Areas
As one of the important raw and auxiliary materials in industry, modified starch can be widely used in papermaking, food, textile, construction and other industries.
1. Modified starch for food should be based on functionality, diversity and convenience. Grain processing requires the development of new varieties, focusing on the development of corn series products, the development of potato starch, modified starch and derivative products; the development of convenience foods, nutritional foods, and emulsifying and thickening.
2. Modified starches used in textile sizing are currently mainly acid-lysis starch, oxidized starch, phosphate starch, etc., as well as a small amount of acetate starch and compound modified starch.
3. Develop new surface coating agents and sizing in the paper industry.
4. Starch-based water-absorbing agents are widely used. Water absorbing agents can be used in agriculture, forestry and horticulture, textiles, papermaking, oil drilling, construction, wastewater treatment, and food processing.
